Biography
Hello! I am currently a research associate in DAMTP, supervised by Prof. Hamza Fauzi.
I received my Bachelor of Science degree at UNC Chapel Hill.
I received my Ph.D. degree in Algorithm, Combinatorics and Optimization from Georgia Tech. I was co-advised by Prof. Greg Blekherman and Prof. Santanu S. Dey.
Research Interest
Convex and real algebraic geometry; polynomial, semidefinite and descrete optimization; applications to quantum physics.
